But first, let me note that these two are terms derived more or less directly from the collaborative work of the French philosophers Gilles Deleuze and Félix Guattari. Now I think it’s important that analytic and continental philosophers learn to talk to each other, and I’m convinced that Deleuze and Guattari’s work, when properly explained, provides a common ground for this discussion. That’s because they provide the ontology and epistemology for a world that is able to yield the results we find in using nonlinear dynamical modeling, as is common practice in quite a few scientific fields today, among them some of special interest to philosophers, such as brain studies. (Varela et al., “The Brain Web” Nature Reviews. Neuroscience 2001 is a review article covering one hundred or so studies of the 1990s that used non-linear dynamics for modeling brain function.).
